2.5 acres

Answer 1

To find the area of the planting land based on the number of seeds Martha wants to plant and the planting density, you can use the formula:

\[
\text{Area} = \frac{\text{Number of seeds}}{\text{Seeds per acre}}
\]

In this case, the number of seeds is 8,000 and the planting density is 20,000 seeds per acre:

\[
\text{Area} = \frac{8,000 \text{ seeds}}{20,000 \text{ seeds/acre}} = 0.4 \text{ acres}
\]

So, the correct answer is:

**0.4 acres**
